Abstract: Based on the modelling system of emission、transport and deposition of the Asian dust storm, Many advanced apparatus and equipments have been furnished by Chinese-Japanese dust storm project in the area of emission, transport and deposition of Asian dust storm. The TSP data is one of the important data obtained. And using meteorological satellite, the cloud graph of the course of dust storm is obtained and the physical parameters of the land surface are retrieved. Because the contributions of different land use/cover are different to emission of dust storm, based on the land use/cover map in the scale of 1:100000, the land surface temperature (LST) is retrieved by the local split-window method. At last, the change curves arranged by time order are formed. Comparing these curves to TSP curves, the results show that they have good correspondent relationship. It can be concluded that there is an affinity between the LST and the dust storm. It is manifestated that the LST parameter retrieved by RS data may become one of the important parameters of the dust storm predict model.

Key words: AVHRR, LST, the Split-window method, TSP Changes
